Web site design crosses multiple disciplines of information systems, information technology and communication design. The web site is an information system whose components are sometimes classified as front-end and back-end.
The observable content (e.g. page layout, user interface, graphics, text, audio) is known as the front-end.
The back-end comprises the organization and efficiency of the source code, invisible scripted functions, and the server-side components that process the output from the front-end.
Depending on the size of a Web development project, it may be carried out by a multi-skilled individual (sometimes called a web master), or a project manager may oversee collaborative design between group members with specialized skills.
